lost power to the radio,dim light and cargo light , checked all fuses with a gage and didn't find anything!! help!!!

Hi and welcome to the forum. If you go up to "User Control Panel" and give us your truck info in the "edit signature" section, it would help us answer any questions you have. I'll assume it's an '02 because of your screen name. All the items you mentioned are controlled by the I.O.D. fuse which is fuse number 12 in the fuse box on the side of the driver's side dash. It's the red (10 amp) fuse with the strange looking black bracket around it. You'll need to pull the fuse out to check it with a meter.

That was It !!! Thank you edcasey!!

Glad I could help.

A lot of people are asking how to pull the fuse from this black clip... (So they can keep it). If you don't want to mess with the clip you can toss it out and push a normal fuse in the hole...
